with the two layers .rolled together toprovidea substantially solidbody, the bodybeing placed in a bag of fabric and restingon a wire-meshbottom placed in the bottom of the bag.

. and arrangement of several parts, to be hereinafter fully described,land illustrated in 4the accompanying drawings and specically pointed outfin the appended claims. i

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which:-v Fig. 1is an elevation with parts in vertical section of the device.

Fig. 2 is a transverse sectional 'view through mg. 1a u Fig. 3 is avertical sectional view through the improved cylinder.

Fig. 4 is a. top plan view of the inner member.

lAs shown in these drawings, the letter A indicates the body of the`illter cartridge which is composed of wiremesh 4I and waste material! orthe like; In carrying out the invention, the layer of waste material isplaced on the Wire mesh and then the parts are rolled into'a cylindricalbody as willbe seen from Figs. 1 and 2, the layers forming spirals. Thebody is placed in a bag 3 v of fabric and a disk 4Il of wire meshis-placed in thebottom of the bag before the body is put in place and Iprefer'to make the upper end ofthe cartridge of dome shape as shown inFig. 1 with the upper end of the bag tting snugly this part of the bodyand suitably fastened at its top as shown in Fig. 1.*

Figs. 3 and 4 show a cylinderfor containing a. cartridge and as shown inthese views, thefcylinder comprises an outer member or tank I Il havingthe cover I I with means, not shown, for providing a tight juncturebetween the cover and the upper end of the tank and within this tankI0,is a smalleng'aging' portions of the upper part of the tank I so asto space thev tanks apart. i Both tanks have rounded lower ends withtheir ends -connected together by a perforated tube I4, the'tube havinga plug I5 threaded in its lower end. The

perforations of the tube communicatawith the space I6 between thebottoms of the tanks and- .aspring-pressed checkvalve Il normally holdsAthe bottom of the inner tank out of communication with the space I6 andtheinterior of the This invention 4relates to a iilter cartridge 4forper tank I2 which has lugs I3 `at its upper end forl tank and rests uponthe bottom I3, the top of the cartridge being covered by a perforatedsubstantially semi-spherical memberr 22.

Thus the oil or other fluid owing from ythe supply or other containerwill pass through the nipple 20 and discharge through the port 2l intothe bottom of the inner tank and -then pass through the opening I9 andthrough the cartridge and then through the member 22 and out through theoutlet 23, When the pressure below the cartridge becomes excessive, saidpressure. will move the `valve `I 'I o its seat so that the oilwillby-pass around the cartridge through the tube I4 and the space I Gandflow outthrough the outlet 23.

Whenffit is desired to remove sediment from the bottom of the tank Ill,the plug I5 can'be removed together with the valve assembly and then theparts can be drained and the sediment will pass through the perforationsin the tube Il.

The oil collecting in the space between the twol tanks willact as acooling medium for the oil passing through the device and as will beseen from Fig. 3, whenthe plug 'I5 is in position, it

covers the lower perforations in the tube I I so.

that the by-passed oil will not disturb the sediment' in the bottom ofthe outer tank but when the plug I5 is removed, the oil and sedimentwill drain from the bottom of the outerl tank through all theperforations in the tube I4. I

It is thought from the foregoing description that the 'advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction aindin the combination and arrangement of the several parts, provided thatsuch changes fall appended claims.

I claim: 1. In a. lter device, a cartridge cylinder comwithin' scope of.the

prising an outer tank, an inner tank'spaced from the outer tank, a-discharge -connection at the top of the outertank, 'a ltering cartridgein said inner tank, means for. introducing theiiuid to be iilteredinto-the bottom of the inner tank below the cartridge', a perforatedtube connecting the bottoms of the two tanks together with theperforations connecting the' interior of the tube with the space betweenthe tanks, and a tank, a ltering cartridge in said inner tank.

means for introducing the ,uid to be filtered irnto thebottom oftheinner tank below the cart'ridge and means for by-pas'sing the uid be-Vtween the tanks when the pressure of the fiuid at the' bottom of theinner tank becomes excessive, such means comprising a. perforated tubein communication with the bottom of the inner tank and' the perforationsplacing the tube' -in communication with the space between the tanks, anadjustable spring-pressed valve normally closingy communication betweenthe tube and the 5 bottom` of the inner tank.

3; In a filter device, a cartridge cylinder comprisingan outer tank, aninner tank spaced from the outer tank, a discharge connectionat the topof the outer tank, a filtering cartridge in -10 said inner tank, meansfor introducing the iiuid tobe filtered into the bottom of the innertank below 4the cartridge, a perforated tube connected,

with the-bottoms of the two tanks with its upper end in communicationwith the 'bottom of the l5 inner tank, and the perforationsv connectingvthe interior of the tube with the space between the tanks, av'alve fornormally closing communica' f tion betWeen..the.- tube andthe inner'tank and) opening'when excessive pressure occurs in the 20 bottom ofthe' inner-tank, some of the perforations in the tube being arranged 'inthe upper portion thereof and some in the lower portion thereof andaplug closing the lower end of thc tube and the lower perforations, saidplug being 254 removed when thel tanks are. to be drained.
